Internship season is fast approaching, and at Chegg, we tend to think that any internship experience is a good thing. You’ll get a chance to explore career options, make connections, improve your resume, and if you’re lucky (or not, depending on your point of view) learn how to rock a business suit. But a recent study by the National Association of Colleges and Employers suggests that, at least from the perspective of getting that dream job once you’re done with school, all internships aren’t created equal.

Specifically, you’re a whole lot better off sticking it out for the paid internship than taking one which has great learning potential, but not great earning potential. In the association’s most recent annual survey of students, 63 percent with paid internships had offers by graduation. Even accounting for gender and industry, only 37 percent of students with unpaid internships were that successful, barely more than the 35 percent of students with no internships who had landed jobs.
